PAPER-DRYING MACHINE.

SPECIFICATION forming part of Letters Patent No. 633,733, datedSeptember 26, 1899.

Application filed April 27,1899.

1'0 (LZZ whom it may concern Be it known that 1, JOHN A. PRINCE, of NewYork, (Brooklyn,) county of Kings, and State of New York, have inventednew and useful Improvements in Paper-Drying Machines, of which thefollowing is a specification.

This invention relates to a machine for forming the printed, varnished,or painted end of a paper-roll into loops and laying such loops side byside upon a drying-rack. The machine insures a reliable delivery of thesupporting-sticks and advances the loops upon the rack by small stages,so that a rapid advance of the loops with a short stroke of the slide isobtained.

In the accompanying drawings, Figure 1 is a side elevation, partly insection, of the machine; Fig. 2, a plan, partly in section, thereof;Fig. 3, a detail side view of part of the rack; Fig. at, a cross-sectionthrough the rack, and Fig. 5 a detail of the gearing e f.

The letter a represents a box adapted for the reception of a battery ofsuperposed sticks or slats b, which may be discharged singly through thelower slotted end of the box.

0 c are a pair of parallel feed-chains, the upper run of which isinclined from the bottom upward. The chains 0 describe a triangularcourse, running over sprocket-wheels c and idlers c 0 of which thewheels 0 are placed below box a, while the wheels 0 are placed directlyin front of a pair of parallel rails d.

To each of the chains 0 are secured two (more or less) pairs of noses awhich by the movement of the chains traverse the lower open end of box ato engage the lowermost stickb and deliver it upon the ends of the railsd, which are supported by hangers d.

Motion is imparted to the chains 0 from a counter-shaft c, havingtoothed wheels 6, which engage smaller toothed wheels f, fast onstub-shafts f, carrying the sprocket-wheels 0 Fig. 5. One of thesestub-shafts is driven by belt g from power-shaft g. Step-pulleys g f onthe shafts g f, respectively, permit the chains 0 to be driven faster orslower, so that the machine may be set for lighter or heavier paper.

The slides for feeding the sticks intermittently along the rails d areconstructed as follows: To the inner sides of the hangers cl Serial No.7l4,640. (No model.)

are secured rolls d upon which are sup ported the reciprocatingslide-bars h. These bars are connected at intervals by rods h, to whichare attached the longitudinal bars or rails 72/2, to which in turn thepawls h are pivoted, one row of pawls being arranged vertically aboveeach of the rails d. Reciproeating motion is imparted to the slide fromwheels c by wrist-pins e pitmen 2', and shaft i, turning in bearings hof bars h.

The forward slide,constructed as described, drives asimilarly-constructed rear slide, the stroke of which is about one-halfthat of the forward slide and the pawls j of which are correspondinglyset closer together. The rear slide receives motion from one of the rodsh of the forward slide by link 70, lever fulcrumed at U, and link itthat engages one of the rods j of the rear slide. The object of the twoslides is that the rear loops of the paper, which are already partlydried, be sus pended more closely together than the front wet loops.

The gearing f c of the chains and the slides should be so proportionedthat the slides complete two or more strokes between the de= livery ofone stick and the delivery of the next stick. Thus in the drawings theslides will reciprocate four times for each complete rotation of thechains, so that while two sticks are delivered the slides will make fourstrokes. The consequence of this arrangement is that the slides will notadvance a loop of paper for the whole Width of such loop during eachstroke, but only for, say, half the width, so that the loops willadvance in small stages and be more thoroughly dried while traveling.

The operation is as follows: A stick I) will be deposited upon ends ofrails d, and the first loop of paper A delivered from roller A will belaid around it. The stick Will now be engaged by pawl 1 and advanced forone-half the space desired. During the next stroke pawl 1 will run idleand the stick will be engaged by pawl 2 and advanced for anotherhalf-space. At the completion of this second stroke anew stick will bedelivered to pawl 1, so that pawls 1 3 5, &c., will alternate in beingactive and idle with pawls 2 4t 6, &c. The consequence is that while thestroke of the machine is small the paper will be moved along rapidly insmall stages to be effectively sticks, and means for driving the chainsand dried. slides at different speeds, so that alternate 10 hat I claimispawls will run alternately idle, substantially A paper-drying machinecomposed ofa pair as specified. 5 of inclined driving-chains havingnoses, a JOHN A.
